A reciprocating piston engine is provided with cyclinders arranged radially about a rotatable drive shaft and a separate piston adapted to reciprocate in each cylinder. Each piston is held in contact with a cam mounted on the shaft by means of linkages and rollers. The cam profile provides greater time for the power portion of the engine cycle than for the exhaust portion of the engine cycle. In a four-cycle engine, greater time also is provided for the intake portion of the cycle than for the compression portion of the cycle.
